Bridgestone to showcase lunar rover concept tires at 40th Space Symposium

Tokyo, Japan – Bridgestone Corporation announced that it will exhibit at the 40th Space Symposium, the United States’ largest space-related symposium. The event is scheduled to take place in Colorado Springs, Colorado from Monday, April 7 to Thursday, April 10, 2025. Bridgestone’s exhibit will be in the Japan’s Space Industry booth, organized by the Japan Aerospace Exploration Agency. Bridgestone aims to accelerate its co-creation initiatives by showcasing the challenge and pursuit of excellence through the development of lunar rover tires, which started in 2019. At the 40th Space Symposium, the Company will showcase two concept models of the second-generation lunar rover tire. These models have been refined from the previous year’s model to feature lower weight, making them suitable for small and medium-sized lunar rovers. These exhibits will serve as a venue for expanding Bridgestone’s space business network and creating opportunities for co-creation.

Throughout its history of more than 90 years of tire development, drawing on its global expertise in supporting all types of mobility on Earth, Bridgestone is now empowering the evolution of space mobility through innovation. Honed in extreme conditions such as motorsports and backed by cultivated expertise, the company is tackling the challenges of lunar exploration, advancing the technology of lunar rover tires as the next stage to surpass its limits. Moreover, Bridgestone is expanding its opportunities for co-creation in this field, as seen in its reaching a collaboration agreement in 2024 with U.S.-based Astrobotic Technology, Inc., a leader in space exploration and technology development. Going forward, the Company will continue its journey to develop tires that can be customized based on the needs of a specific customer or mission, supporting safety, peace of mind, and the challenge of humanity in lunar development from the ground up.

The lunar rover tire development project is an initiative to expand the utilization of technologies developed in relation to the “AirFree Concept,” which has been positioned as an exploratory business in Bridgestone’s Mid Term Business Plan (2024-2026), from Earth to outer space and the lunar surface. In the future, the Company aims to apply the technology refined in the extreme lunar environment to tires used on Earth, thereby contributing to further value creation.

In addition to exhibiting a concept model of tires for small and medium-sized lunar rovers at its booth, Bridgestone is also scheduled to take part in a collaboration panel together with Toyota Motor Corporation, Idemitsu Kosan Co., Ltd., and symposium organizer Space Foundation.
